When people made passing comments to Daegan Coyne that her baby bump was ‘way too small’, she started to wonder if everything was okay.

The Gold Coast mum-to-be is pregnant with her first child, and despite being told by doctors her baby’s size is in fact above average, peoples comments had her scared.

The experience prompted her to speak out and say there is no ‘one size fits all’ when it comes to pregnancy, and told Daily Mail Australia women should not compare their bump with others.

Individual: The fitness advocate wants other mothers to not compare their bumps with those they see on Instagram

Nothing to worry about: Mrs Coyne said doctors told her her baby girl is bigger than average

‘I have had pregnant friends called out for being “too big”, others “far too muscly” and myself, the “you’re way too small”,’ she said.

‘Given I am yet to see one lady carry their pregnancy shape and size the same as another, I believe it’s safe to assume peeps [sic] that there is no “one size fits all” pregnancy.

‘I know heaps of the comments aren’t meant to be hurtful or upsetting by any means, but we all have enough to worry about being a new mum … let alone whether you are the size you are “expected” to be.’

Baby on board: She said at 24 weeks pregnant she ‘looked like a lot of people’s full term’ and would receive many comments about her size

Mrs Coyne is friends with fit mums Revie Jane Schulz and Chontel Duncan, who both attracted comments about the size of their bumps during pregnancy.

On Tuesday Revie shared a throw-back photo to when she was 24 weeks pregnant, where she said she: ‘looked like a lot of people’s full term’.

She said people regularly told her her bump was ‘huge’, and the comments made her want to hide away and at times reduced her to tears.

Compare the pair: Chontel Duncan’s photo compared her bump at 21.5 weeks pregnant with her friend Nat’s who was four weeks further along

Chontel Duncan made headlines for having abs while pregnant, and a photo that compared her bump at 21.5 weeks to that of a friend’s four weeks further along in their pregnancy went viral.

Mrs Coyne said women should not compare their own baby bumps to those they see on Instagram, and there is no perfect size for all pregnant women.

‘We want to make it known that every single person carries their pregnancy differently,’ she said.
